Thank you, Vibhuti. Good afternoon, everyone. Now I would like to review the results of the first quarter of fiscal year 2026. Net revenue for the quarter was $299.1 million, which is above the high end of our guidance range of $290 million and $298 million. Revenue was up 3% sequentially, and on a year-over-year basis, was up 25.6%. Operating margin for the first fiscal quarter was 15.7%, above the high end of our guidance range of 14.6% - 15.4%. Operating margin increased 130 basis points from the prior quarter, and on a year-over-year basis, was up 570 basis points. EPS at $0.15 was also above the high end of our guidance range of $0.13 - $0.14 and was up $0.02 sequentially. On a year-over-year basis, EPS was up $0.09. Moving on to our Q1 results by business segment. NSC revenue for the first fiscal quarter came in at $216 million, which is above the high end of our guidance range of $208 million to $214 million. On a year-over-year basis, NSC revenue was up 35.5% as a result of strong demand for lab and production, as well as field products, and was mainly driven by the data center ecosystem, as well as the acquisition of Inertia Labs. NSC gross margin for the quarter was 63%, which is 210 basis points higher on a year-over-year basis, and primarily driven by higher volume and favorable product mix. NSC's operating margin for the quarter was 7.5%, compared to negative 4.6% during the same quarter last year. NSC operating margin was above the high end of our guidance range of 5.4% - 6.2%, primarily driven by higher fall through. OSP revenue for the first fiscal quarter came in at $83.1 million, which is in line with our guidance range of $82 million - $84 million and was up 5.5% on a year-over-year basis. The increase in revenue for the quarter was primarily a result of strength in anti-counterfeiting and other products. OSP gross margin was 52.3%, down 300 basis points from the same period last year, and was mainly due to unfavorable product mix. OSP's operating margin was 37.1%, which is below our guidance range of 38.1% to 38.5% due to product mix and higher manufacturing costs. The operating margin decreased 250 basis points on a year-over-year basis. Moving on to the balance sheet and cash flow. Total cash and short-term investments at the end of Q1 were $549.1 million, compared to $429 million in the fourth quarter of fiscal 2025. Cash flow from operating activities for the quarter was $31 million versus $13.5 million in the same period last year. CapEx for the quarter was $8.5 million versus $7.3 million in the same period last year. During the quarter, we successfully refinanced our $250 million, 1.625% three-year convertible notes due in March 2026, with $250 million, 0.625% five and a half years convertible notes due in March 2031. As part of this transaction, existing convert holders exchanged about $100 million for the new convert, and the remaining $150 million raised will serve to pay off the balance of the March 2026 convert. This remaining $150 million is included in the cash balance of $549 million at the end of the first fiscal quarter of 2026. In conjunction with this transaction, we purchased approximately 2.7 million shares of our stock for about $30 million. We have almost $170 million remaining under our current authorized share repurchase program. The fully diluted share count for the quarter was 227.9 million shares, up from 224 million shares in the prior quarter, and versus 228.6 million shares in our guidance for the first fiscal quarter. Moving on to our guidance for the second quarter of fiscal 2026. In mid-October, we successfully closed the acquisition of Spirent 's High-Speed Ethernet Network Security and Channel Emulation business lines from Keysight. The acquisition of these business lines is expected to add about $200 million of annual revenue run rate, which is above our prior estimate of around $188 million. We also concurrently closed the previously announced $600 million term loan B, which was used to fund the transaction at close, as well as general corporate purposes. In addition to the acquisition of Spirent 's business lines, we expect the second fiscal quarter revenue for VIAVI to reflect continued strength in many of our end markets. Our guidance includes financial performance of Spirent's business line for approximately 10 weeks. For NSC, we expect continued strong demand for lab and production, as well as field products driven by the data center ecosystem. For OSP, we expect quarter-over-quarter revenue to be lower in line with seasonality of lower demand for both anti-counterfeiting and 3D sensing. For the second fiscal quarter of 2026, we expect VIAVI revenue in the range of $360 million and $370 million. We expect total NSC revenue between $283 million and $293 million, including revenue from Spirent between $45 million and $55 million. OSP revenue is expected to be approximately $77 million. Operating margin for VIAVI is expected to be 17.9%, ± 60 basis points. Total NSC operating margin is expected to be 13.6%, plus or minus 70 basis points. This includes Spirent's contribution, which is expected to be slightly accretive to existing NSC margin for this quarter. OSP operating margin is expected to be 34%, ± 50 basis points. EPS is expected to be between $0.18 and $0.20. VIAVI's standalone EPS is expected to be about $0.18, and we estimate Spirent's contribution to EPS is in the range of $0 - $0.02 after allocating pro-rata interest on debt. Historically, Spirent's HSE revenue has been stronger in the second half of the calendar year. This strength in revenue is reflected in the guidance for the fiscal second quarter. We currently plan to leverage the complementary product portfolio and capabilities and report NSC as one business segment going forward. Our tax expense for the second quarter is expected to be around $10 million, ± $500,000, as a result of jurisdictional mix. We expect other income and expense to reflect a net expense of approximately $12.2 million, which increased mainly due to the interest on the TLB, and the share count is expected to be around 228.7 million shares. With that, I will turn the call over to Oleg. Oleg? Thank you, Ilan. The first quarter of fiscal 2026 saw the continuation of strong momentum from the fourth quarter of fiscal 2025, coming in above the high end of our guidance. It was also significantly up year-on-year and countercyclically up quarter-on-quarter. NSC revenue in Q1 grew approximately 35% year-on-year, primarily driven by strong demand from the data center ecosystem and aerospace and defense customers. The data center ecosystem, which includes high-performance SAMIs, optical modules, and NAMs, drove strong demand for lab and production products in support of the AI data center build-out. We saw strong demand across all optical networking product lines, the 800 gig and 1.6 Tb Ethernet test, chip-to-chip interconnect and protocol test, and a broad range of production test equipment. In addition, we are now also seeing a growing demand for our traditional field instruments by hyperscalers as they build out and operate their new AI data centers. We expect this strong momentum to continue well into fiscal 2026. Lastly, with the recent acquisition of the highly complementary Spirent's High-Speed Ethernet product line, we have further strengthened our position in the data center ecosystem, significantly increasing our business footprint there. Our aerospace and defense business also saw another strong quarter of growth, driven by continued high-end demand for our positioning, navigation, and timing products. We expect the strong demand to continue throughout fiscal 2026. The service providers' business was generally stable during the quarter. The gradual recovery in fiber was mostly offset by the continued soft demand for wireless products. We expect this trend to continue in the medium term. Looking ahead, we expect strong quarter-on-quarter growth in NSC, driven by both the continued strong demand from the data center ecosystem and aerospace and defense customers for VIAVI Classic products and the incremental revenue from the recently acquired Spirent product lines. Now turning to OSP. OSP saw strong year-on-year revenue growth, driven mostly by recovery in anti-counterfeiting and other products. The 3D sensing demand was in line with seasonal expectations. We expect fiscal Q2 to be down quarter-on-quarter, in line with the seasonally lower demand for both anti-counterfeiting and 3D sensing products. In summary, we expect the strong start in Q1 to continue throughout fiscal 2026, supported by the stabilization and recovery of our mature end markets, including the service providers, anti-counterfeiting pigments, and 3D sensing, and the continued strong demand by the data center ecosystem and aerospace and defense customers. In conclusion, I would like to welcome our new employees to VIAVI and thank the VIAVI team for its continued strong innovation and execution. Lastly, I would also like to thank our customers and shareholders for their continued support. With that, I will now turn it back to the operator for the Q&A. Thank you. The floor is now open for questions. If you have dialed in and would like to ask a question, please press star one on your telephone keypad to raise your hand and join the queue. If you would like to withdraw your question, simply press star one again. If you are called upon to ask a question and are listening via loudspeaker on your device, please pick up your handset and ensure that your phone is not on mute when asking your question. One moment for your first question. Your first question comes from the line of Ruben Roy of Stifel. Your line is open. Hi, Oleg and Ilan. Thanks for the questions and great to see the progress and congrats on the closing of the Spirent business. I guess the first question, Oleg, would be, as you continue down the road of diversifying your revenue, maybe you can give us an update of what the mix is, if you think about your kind of core telecom service provider revenue in NSC versus some of the new products that you're selling at the hyperscale. Obviously, you've been talking a lot about aerospace and defense doing very well with expectations for continued growth. Maybe you could just give us the mix as a first question. Thank you. Sure. Thanks. I would say if we look at our exit of the fiscal year, we did about 50/30/20, so 50% service provider, 30% data center ecosystem, and 20% aerospace and defense. Now, as we close the Spirent business, it's about, what, 45%, about 40%, and then the remainder, so 45% is service provider, 40% data center, and 15% aerospace and defense, purely as you average it out. We are now getting to the point where the data center revenue is almost approaching the traditional service provider, which significantly de-risks the volatility of the service provider spend, and the aerospace and defense continues to grow as well. I think, as we look forward, we are going to probably, I would say, exiting this year, we may see data center ecosystem surpass the service provider, and service provider will still grow, but it's growing at a much lower rate than data center, and our aerospace and defense will also continue to grow. We'll have a much more balanced portfolio and less, I would say, dependent on the neurotic service provider spend. Great. Thanks for that detail, Oleg. If I take Spirent out of the guidance, it looks like my math is right. You're still growing around 10% sequentially on that core NSC business, almost 20% year-over-year. I was wondering if you could maybe break out, given that service provider is still sort of mixed with wireless, still having some headwinds, etc. If you think about that growth on the core business, can you break it out between sort of what you're seeing in data center versus the aerospace and defense business? Sure. I think when we look at data center, we look at everything that falls into data center. We're going to see a very strong demand, believe it or not, for our field instruments, but it's field instruments by the data center ecosystem. It's these specialist fiber companies that are doing now intraconnect. You probably saw some very interesting dynamics with NVIDIA investing in Nokia. I can kind of elaborate on that. What we are seeing is, initially, it was all about building out data center. Then they realized the fiber interconnect between data center is crap. They said, "Okay, we cannot accept the traditional fiber network provider." There's been a significant investment and emergence of the specialist fiber interconnect companies that are now spending quite a bit of money, really improving the reliability and performance of the fiber networks. We're actually seeing that is driving also the revenue of our traditional, what we call field instrument business. Of course, the classical data center, you know, the 1.6 Tb, 800 gig, the production optical production test equipment continues to grow very nicely into the December quarter, and there's going to be an additional momentum building as far further into the March quarter. Aerospace defense will continue to gradually grow on a continued basis that it has been doing. The only, I would say, kind of the cylinder in our engine that is still fairly weak is the wireless business due to the wireless spend dynamics by the major wireless carriers. You saw a very interesting thing. Just as we said about two years ago that eventually somebody will wake up that the fiber is awful and they'll start investing in fiber, and that's already happening now. This whole thing is trickling down from data center into fiber networks. The next bottleneck that is not ready for the whole AI ecosystem is the wireless RAN. That's why, actually, we were not surprised at all that NVIDIA put in $1 billion into AI -RAN in Nokia. We do hope, I mean, we are seeing that's really accelerating the 5G advance and 6G development. It will likely pull this in closer. We know the others are seeing it, and they're also going to start scaling their investment. We do think our wireless business probably will be kind of the last cylinder in the engine to turn on into the next calendar year. That kind of hopefully gives you a good color on all the elements of the NSC business. Yeah, absolutely. Thanks, Oleg. If I could sneak one in for Ilan, great to see the operating margin guidance for NSC. Obviously, Spirent is starting to contribute there. Can you give us maybe how you're thinking about operating margins as you sort of run-rate the business to full quarter, you know, kind of exiting fiscal 2026 and into fiscal 2027? Thanks. Thank you for the question, Ruben. Currently, including Spirent, we are towards kind of the $160 million a quarter. I believe, you know, that obviously we are still working on or just starting to work on integration, etc. Probably for, you know, the early part of 2026 calendar, it can reach, you know, maybe $5 million higher or so at around, you know, the $165 million range. Okay, thank you. Sure. The next question comes from the line of Mehdi Hosseini of SIG. Your line is open. Yes, thanks for taking my question. Two from my end. Oleg, let's assume wireless doesn't come back, kind of a worst-case scenario. Given the Spirent and a baseline assumption that it would be $0.08 accretive and a strength in fiber and perhaps a slightly higher growth rate for a smartphone next year, it seems to me that you should be exiting calendar year 2026 at close to like $1 annualized EPS. If wireless were to come back, there will be growth above that target. I'm not asking you for a guide, but given the scenario you laid out, wireless could come back and just be extra and help you with a higher earning power. Any thoughts here would be great. As you can see, just as our business started tanking from the cutback in service providers in 2022, we had a significant operating de-leverage. Now that we're going in the other direction, we're getting significant operating leverage where every incremental dollar just drops right to the, you know, a big chunk of it drops to the bottom line. You're right. Getting up to if things continue as they are, it's entirely possible we'll be running around close to $1 a share next year. You know, your words and God's ears. You're right. Wireless is a significant incremental catalyst once it gets going because it's really been one of the segments that's kind of been left behind in this whole recovery. Clearly, as it starts turning around, it will be a major contributor to the bottom line. Okay. Great. Just double-clicking on the OSP and given the upcoming changes to the form factor for a smartphone application, should I assume that some of the past pricing pressure is going to abate and go away, and at least you should have some operating leverage there without contemplating what the real smartphone unit growth would be? Sure. I think you're right. I mean, it's a more maturing segment. The volumes, you know, we're fairly saturated in that market. The only incremental growth comes from the unit growth and maybe greater adoption of the world-facing 3D cameras. We're seeing actually also incremental upticking of the facial recognition technologies with the Android players in Asia. Not the big ones like Samsung, but it's mostly the Chinese. We do think it will provide some additional growth. There we sell wafers to module integrators, so it provides a bit more leverage there. Also, the automotive market with LiDAR in Asia is becoming a big consumer of the 3D sensing filters. Now, we got to put it in perspective. It's kind of hard to compete with 300+ million units. Automotive is like maybe 10 million. Let's say it's a nice welcome growth in the unit volume. In terms of the ASP erosion, I think it's fairly stabilized at this point. I'd say the volume is the only thing that matters right now in terms of growing the revenue in that segment. Okay, thank you. Your next question comes from the line of Ryan Koontz of Needham & Company. Your line is open. Great. Thanks. If we could double-click on the data center opportunity, I think that's been a little bit of a quiet market for you in terms of, I think, investors understanding your exposure there. Great to hear you're working that up. Oleg, do you feel like your execution in that customer segment is where it needs to be today? Do you need to invest more in go-to-market? Do those customers have different product requirements that you might need to respend new products for data center, or is it largely the same products as your traditional service providers? It's a great question. We've been investing in this business for the last three years. The term that I've borrowed from distribution business is churns and earns. Let me just clarify what it means. What we're seeing today, as we shifted from telecom service providers driving the roadmap to the data center driving our roadmap, you're going from anywhere six to eight years between the generations of products to about two to three years. You have a very much faster turnover of the technologies. It means you got to deliver your products now every two to three years. Also, because it is driven by engineering labs and new product development, it comes in at a much higher margin. You are turning the product portfolio much faster, which means you don't have this like a long volume waiting for the next generation. You're earning higher% gross profits because it's a, you know, first-to-market always wins big. In that respect, we really like it because it's increasing the size of the market for us, and it's accelerating the revenue velocity for us. We get paid for the value we deliver by being always the leader in this market. The reason I use the word data center ecosystem is because our products don't just address a particular segment. We address everything along the entire value chain. It's your processor companies, you know, you'll know who they are. It's your physical layer communication companies like SerDes and the module integrators. It's your system companies, optical gear like [CIAN, RISO, Cisco], and so on and so forth. It's actually ultimately the actual hyperscaler who have extensive internal R&D developing anything from optical modules to MEMS switches to full-blown data center equipment. This is like the best thing you can have. You're dealing with engineering budgets and the intense competition where everybody's trying to be first-to-market with a better technology. This is like, you know, truly living inside a tornado. Our team loves it because that actually plays very well to our traditional strength to be at the bleeding edge of bringing leading-edge technology to the optical networking. That's super helpful. Would you say, Oleg, you have. Actually, you know, I would add one more thing. Sure. I would add one more thing. We talk always about speed. So 400, 800, 1.6, 3.2. That's a network speed. What you also have in parallel is chip-to-chip interconnect. You go from PCIe 3.0, 4.0, 5.0, today in 6.0, and then it will be next year 7.0. Every time you move to a higher speed, you need a corresponding PCI Express next standard as well. It's a tick-tock. You deliver your network speed, which immediately needs a wholesale replacement of all the chip-to-chip interconnect. That's a force multiplier on that whole data center growth. Yeah, that's really great. Would you say you have a similar set of competitors and similar share in the data center relative to your legacy customer base? I would actually say where we play, you know, at purely the layer zero, layer one, we have a significantly greater share because that's traditional strength of JDS Uniphase, VIAVI. We were very strong in it. With the acquisition of Spirent, we have now added layer two to layer seven capability as well. There, you know, let's say there's two major competitors in that space. I mean, clearly, one was Spirent, and the other one is Keysight through their acquisition of Ixia. I would say, you know, today it's VIAVI and Keysight that are big players in that space. You know, there's about maybe four or five additional smaller players playing in individual layers kind of, you know, all over the world. It's very much, I would say, two major players because the level of intensity and speed with which you have to bring out the products, it's not a low-budget game. It drives quite a significant R&D spend. I would say in that particular space, I'd say it's Keysight and VIAVI. Great. Maybe just a follow-up if I could on the aerospace and defense area. Can you kind of characterize those products? Are those P&T modules you're selling in typically, or what's the fulfillment model look like? You're selling to drone companies and the like or defense companies? Yeah. It goes into everything. We have a smorgasbord. We can sell you inertial measurement units. It looks like a chip in a specialized package. We can sell you a module that has multiple of these chips with a controller and logic that does the inertial navigation system. We can sell you a full-blown inertial navigation system with sensor fusion, receiving sensor data from cameras, the satellite antennas, and everything else. We have a full solution. Depending on which customer we engage and what their relative capabilities are, we'll sell them individual components. We sell them the modules, or we sell them the complete solution. If you're looking at some of these drone companies, I would say in Central and Eastern Europe, they may buy the entire solution. If you're dealing with a more sophisticated U.S. company, they may be buying modules or individual components that go into their critical systems. It's all about autonomous vehicles, air, ground, sea, or undersea. You name it, that's what we are servicing. The nice thing about it, it's the same platform that can address all these different markets, including the mining, agricultural, and surveillance drones, and all these things that you need if you think about the fully GPS-independent, autonomous kind of robotic vehicles. Again, if you have a question, please press star one. Your next question comes from the line of Michael Genovese of Rosenblatt Securities. Your line is open. Thanks. Oleg, I think my phone broke up because I think you gave a new annual revenue number for the HSE acquisition, but I just didn't hear what it was. Yeah, Ilan will. Yeah, go ahead. Currently, once we closed the transaction, we got a little bit more insight. Currently, on an annual run rate, we believe it's about $200 million, including the emulation piece, the channel emulation. Prior to that, we thought more about $188 million. Yes, it is higher right now. Okay, I guess my question is. You're in the Spirent business, right? My question has to do with, you know, does that change on higher revenue or any other reason, you know, kind of bring an accretion date sooner than 12 months, or are we still thinking 12 months before it becomes accretive? It depends also on seasonality. Remember that there are stronger half is on the second calendar half. That's the reason that this quarter we see some positive EPS. Most likely in the first calendar half, it's a little bit softer. When you think about it from a full calendar year, yes, it's slightly higher. When you compare it to our fiscal year, the dynamic changes a little bit. Yeah, that's clearly higher revenue makes the accretion sooner rather than later. Great. I think most of my questions were asked, but I just want to ask specifically on large service providers like AT&T, Verizon, or the cable companies. If we look at the wireline part of the network, we heard weak wireless from you on that. It sounds like a lot of the optical activity is being done by optical specialists. Is there anything to say about the tier one large cable and telcos on the wireline side? Is there any trend there that you can call? Yeah, I would say gradual recovery. I mean, fiber is growing. We do know there's going to be some big RFPs coming out from major cable operators and the service providers. It's more with I'm now looking, when I look at the fiber, we are now starting to segment them into professional-grade fiber operators and kind of consumer-grade. AT&T is more of a consumer-grade. They just continue, like, you know, they keep talking about adding a lot of fiber customers. That actually is great news to us. I just want to hear, when I see the money, I'll believe it. I mean, they did make some pretty bullish announcements. We do think next year there will be accelerating some buying. It all plays very well. There is also this whole category of what I call professional-grade fiber operators, emerging companies like Lumen. There are similar companies in Europe who all they focus on is interconnecting all these data centers. I'd say the next one will be how do you connect them all to the wireless base bands, I mean, base stations, to the towers? You now need to bring a reliable 10 gig, 100 gig traffic to all the towers. We do expect the combination between the traditional and these professional-grade fiber operators to continue to grow nicely into next year. Even, you know, take the base, the base business, the traditional service providers, it's all goodness because it's a high tide that raises all the boats. We kind of call it as a base business. All these other companies, we call them speedboats. It's your professional-grade fiber operators, the SAMIs, modules, NAMs. These are all kind of speedboats that are growing much faster than the overall market. It is encouraging to see even your base service providers starting to spend more money. All right. Great. Thanks for the call. Sure. Thanks. Your next question comes from the line of Andrew Spinola of UBS. Your line is open. Thank you. It's just one for me. Wondering if you could provide a little bit more color on the business, the Spirent business that you acquired. Was the margin profile on that business, you know, consistent with the overall business? Was it better or worse? When I'm thinking about modeling that, you know, post the 12 months when it turns accretive, do you think you can drive the margin in that acquired business in line with maybe your targeted 20% for NSC, or do you think you can do better? How should I think about that? I think that business is both higher gross margin than the average NSC, and it's higher operating profit than average NSC. It's net-net accretive. I do believe that through integration and greater efficiency, we can actually expand their margins further. I think we do have a, I think on cost of goods, we should be doing a lot better because we have now greater scale in the parts procurement and greater leverage of engineering and sales resources. Andrew, just specifically on the gross margin, we see it in, you know, from the mid to high 60%, which is, as Oleg mentioned, definitely above our corporate average. It's a nice contribution there. Got it. Is that business seeing the same acceleration that you're seeing in the rest of your data center business? Yes. I mean, probably not the same percentage because it's from a much bigger base. Absolutely, they have a very exciting product called, there's a traditional HSE, High-Speed Ethernet test that you sell to chip companies, the modules and systems, and enterprise data centers. There's a whole different flavor called AI HSE, which tests, generates AI workloads. You can test your network on how good it is to run the AI traffic and AI data. That piece is growing even faster. I see. I wanted to ask one last question, actually, on the data center business. I'm trying to think about that business in terms of units versus, you know, what other growth drivers you might have. How much of that business is, you know, if the number of switches being produced is doubling, tripling, what have you, how does that translate to benefits for you? Are you seeing most of your growth because of the growth in units in these products, or is it that there's just a lot more investment in R&D, new SKUs, new players in this space? How should I think of that? It's a combination. When we talk about sales to the lab, i.e., to the R&D equipment, it's number of companies, number of projects, number of chips. Remember, I also said the very fast product churn cycle, right? Like every two, three years, next generation. That drives the more like the lab sales are driven by projects, right? It's number of companies, number of projects, and how quickly one generation transitions to the next. When we talk about production, that is driven purely by units. The more units you're producing, the more you're shipping, the more you need to buy to set up more production lines. This is more like if you think about contract manufacturers, the more lines they add, the more equipment they need to buy. What's the split in your business between unit-driven business versus project-driven business on the data center side, roughly? You know. We don't really split it. That's, you know, dicing it very thin because it's effectively the same product, the same technology, packaged into a different box. Got it. Thank you very much. Sure. Thank you. Your next question comes from the line of Tim Savageaux of Northland Capital. Your line is open. Hey, good afternoon, and congrats on the results and the guide. I want to focus in on there in particular. First, on Spirent, you mentioned the larger base. Interested in what context you meant that. It sounds like, given what you're guiding to, and I don't know if you're 50/30/20 going to 45/40/15, I'll just assume that's fiscal 2025 versus fiscal 2026. It seems like Spirent's got to be well above 50% exposed to data center. Yeah, what I [crosstalk]. Is that fair to say? Go ahead. Yeah. The percentages gave it, that's exiting this calendar year. It's like exiting December, the mix, including now the new Spirent business. In terms of their exposure, I would say if I define the data center ecosystem, the lion's share of their business is data center ecosystem. They also have an enterprise data center. When I say data center ecosystem, it's chips, modules, systems, and hyperscalers. They also have the enterprise, like, say, financial insurance and other companies with their own where who test their own firewalls and things like that. That's, I would say, probably like an 80/20 split, probably. Okay. That makes sense. Looking at the organic guide, which is still, you know, pretty impressive, I guess, you know, $310 million -$320 million, and understanding you're getting a healthier Spirent contribution despite the shortened time period. You explain that. As you look at that, and kind of asked this a little bit before, we've seen some pretty good numbers in terms of what some of the big U.S. carriers are looking to spend in Q4. I might have looked at that organic number and thought, you know, an old-fashioned budget flush. Apparently not. It doesn't look like you're building much in there. Am I right? For the traditional tier one telecom providers, are you looking at that to be a challenge? For traditional Q3 to Q4, no, there is some incremental growth for traditional. Sorry, for the traditional. [Crosstalk] Go ahead. Sorry. For traditional, there is some incremental growth, but I won't say budget flush. The incremental demand is coming from what I call the professional-grade kind of tier two, tier three focus players. You can call it budget flush, but I think their stuff is driven by projects that they and contracts that they've signed with hyperscalers. What we are seeing now increasingly, what we used to call, you know, you'd have field instruments where we would sell 90%+ to service providers, we're now seeing a quarter up to a third of revenue is going into the whole data center-driven service provider ecosystem. You look at that organic growth going September to December. Yeah, we all see Verizon and AT&T saying that next year they're going to expand. If that happens, that will be just like a further tide that will raise all the boats. Got it. It looks like anything good happening with the tier one. Tim, you know, also we're not guiding for March, but it's not that we see anything materially different going into March. The only thing I say about tier ones, every quarter percent drop in interest rate frees up a whole lot of cash for them to do things. There's a lot of pent-up demand. Basically, it's like they've been sweating the assets for the last three to four years. These things, like anything else, wear out. It needs to be updated. I do think as they're getting a little bit, they're feeling better and more comfortable with the debt load, the interest load. They've all been sending all the right signals. That's actually quite encouraging. That's a positive thing for us. It would be a further, I would say, accelerator or a boost to the overall demand. Great. Thanks very much. Congrats again. Sure. That concludes our Q&A session. I'll now turn the conference back over to Vibhuti for closing remarks. Thank you, Jael. This concludes our earnings call for today. Thank you for joining. Have a good evening. This concludes today's conference call. You may now disconnect.
